Application filed August 4, 1884. (No model.)

T0 aZZ whom it may Cancel-n,.-

Be it known that I, JOHN H. WALKER, of Waterbury, in the county of New Haven and State of Gonnecticut, have invented a new Improvement in Buttons; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a vertical section of the button, showing a side view of the bar; Fig. 2, a vertical section transversely across the bar; Figs. 3 and 4, illustrations of previous constructions; Fig. 5, the bar-piece or disk,as cut from sheet metal prcparatory to bending; Fig. 6, a section of Ithe bar-piece on line a; x, showing the outer flange as turned down; Fig. 7, a section on line y y, the outer fiange turned downward;

Fig. 8, a section on same line,yy, with the tongucs m turned downward to round the bar; Fig. 9, a section on line z z after. the tongues have been turned down; Fig. 10, a section of the bar-piece, showing side view of the bar; Fig. 11, a'modification of the bar-piece.

This invention relates to an improvement'in. that class of buttons eommonly called suspender-buttons7 and to that particular division of this class in which a bar eXtends across the central opening in the button over which the stitches are taken to secure it to the garment, commonly called bar-buttons.,7 The button consists of a front, a, and a back, Z), the two of cup shape and so as to set one within the other, the front closed over the edge of the back to secure the parts together. The bar in some cases is made of wire bent into S or other shapc, and introduced between the front and back, so that wire will pass diametrically across the central opening in the button, and secured by closing the front and back together. In other cases the bar is made from sheet metal. This is done as seen in Fig. 3, the disk dbeing cut from sheet metal of substautially the internal diameter of the parts of the button. At the center two nearl'y semicircular cuts are made, in diameter corresponding substautially to the diameter of the opening through the button. The ends of these scmicircles do not quite reach each other, but so as to leave a central part connected, and forming atongue,

c, each side the center. These tongues are then bent down, as seen in Fig. 4, forming a bar across the center, which-presents a rounded upper surface. In the mauufacture of this bar a serious difliculty and considerable loss exists, from the fact that in cutting and bending the cars c e downward, the connected portion between them frequentlybreaks from the disk, and particular] y is this the case unless the metal be of the finest quality. In common sheet-tin 'such breaking is of frequent occurrence. If il' does not entirely break away, it cracks the metal so 'as to present a rough edge at the ends of the bar, against which the thread willwear and be quickly cut.

the bar from sheet metal, but avoid this difficulty of breaking; and it consists in the construction of the disk from which the bar is formed, as more fully hereinafter described, and partieularly r'ecited in the claims.

The disk f is cut from suitable sheet metalcommon sheet-tin, for illustration as seen in Fig. 5. Instead of simply cutt-ing` a slit to form the tongue each side the center, as in the previous construction, .I cut a semicircular slot, 71,, each side the center, the endsiof the slots leaving solid metal between them, as at i. The internal diameter of the semicircular slots is substautially that of the opening Z through the front a of the button, and so as to leave a `into each of the slots. The disk is made of larger diameter than the internal diameter of the button, and theouter edge of the disk is turned downward to form a flange, a, around the edge of the disk. The projecting parts m m are turned downward, as seen in Fig. 8, so as to round the upper edge of the bar between the connections z' i, this rounding of the upper surface extending onto the connections i as seen in Figs. 9 and 10, the round dying out on those connectionsi before it arrives-at their point of .connection with the surrounding portion of the disk. Bythus forming the bar the tearing strain upon the tongues at their intersection with the disk is avoided, the rounding operation being gradual from the flat disk onto the central portion of the bar. The connection between'the bar and its diskis carried so far tongue, m, on the central portion projecting.

The object of my invention is to construct v IOO in beneath the front that the thread cannot each beyond the full roundcd surface of the While I prefer to inake a complete disk, as seen in Fig. 5, the side portions of the disk may be cut away, as seen in Fig. 11, leaving at each end sufficient support for the bar between the two parts of the button.

In making np the button the bar-piece is introduced into the back, as seen in Fig. 1, and then the back closed thereon, so as to finnly hold and grasp the bar-piece between the front and back.

While I'prefer to construct the bar-piece Withthe flange n around its edge, that flange may be oniitted.

I claim- 1. rlfhe combination of thev front a andvback b With the bar-piecef, arranged between the front and back, the said bar-piece constrncted With tongues m m in its central portion, With a narrow connection7 at diametrically-opposite ends of said central portion, uniting said central pQrton With the onter portion of the bar-piece, the said tongues bent downward, snbstantially as described.

2. The combination of the front a and back b, intermediate disk,f, constructed with semicircnlar concentric slots h h, to form central tongues, m m, and narrow conneotions 'i i, between said tongues and the surrounding .portion of the disk, the said disk construoted with a fiange, n, around its edge, and the tongues m m turned downward, snbstantially as de soribed.
